Compatible Cameras: Sony FS7/ FS5/ A7S/ A7S Mk2/ A7R/ NEX Series
The Sony 28-135mm G lens gives you a very useful range, ideal on the A7S, although with the smaller chip on the FS7 it’s a little bit long at the wide end. However, after doing a direct comparison with the Canon L-series lenses and a speedbooster, I was very surprised at how much sharper the Sony lens was, particularly with dark areas. It was such a difference that we initially thought we had a dodgy Canon lens or speedbooster. We tested this with another Canon lens and speedbooster on the premises and got exactly the same result. I think it’s because of the fact that Sony lenses are optimised to Sony cameras, but it definitely makes you think about the choice of zooms to use.
Don’t be put off by the f4 aperture, these are very sensitive cameras and with a large chip you would rarely want a depth of field that is shorter than you can get with an f4 lens. The obsession with wide aperture lenses dates back to film days, when we were having to deal with very insensitive materials, and having a wide maximum aperture would determine whether you could shoot at all in certain situations.
The wider the aperture, the more difficult it is to design the lens, and the more expensive it is as a result. A wide aperture lens is always a compromise and a lot of the f1.4/f1.5/f2 lenses suffer from being a bit woolly around the edges when wide-open. For optimum performance f5.6 is the best stop to shoot at. As with all these lenses, they are predominantly designed for autofocus, and therefore are not ideal if you want to pull focus or for use with a follow focus, although possible.
Full Frame G Lens for pro moviemaking
Inheriting technology from Sony professional equipment, this lens boasts a precision optical design that supports 4K as well as upcoming high-resolution formats with minimum breathing and image shift. Three control rings offer manual control for demanding large format production, and the first SSM drive in a lens designed for movies contributes to quiet powered zoom.
